A triangular pyramid has four faces, four corners (or vertices) and six edges in total. It falls under the designation of a tetrahedron because it has four triangular faces. If all the triangles are identical equilateral triangles, then it is a regular tetrahedron. To calculate the volume of a triangular pyramid, a person would multiply the base area by the height of the pyramid and then divide by 3.
